Answer 1

Answer:

  3

Step-by-step explanation:

You want to evaluate the expression (8ab)/(2bc) for a=3, b=12, c=4.

Evaluation

Put the values where the corresponding letters are and do the arithmetic. Here, some factors are obviously cancelled, simplifying the problem.

  $\dfrac{8ab}{2bc}=\dfrac{8\cdot3\cdot12}{2\cdot12\cdot4}=\boxed{3}$
